100% satisfied. My lens was perfect in every way. Doggone good buy.
It is a Screw mount lens with adapter. It fits both of my old 35mm cameras, the Pentax K- 1000, and my Vivitar 4000s. Both manual cameras from back-in-the-day, ya' heard me?
- good focus range
- 2x tele converter and 3 filters
- decent size good handling
- despite its big focal lenght good close focusing (less then 2m!)
- requires a lot of light (fixed f/8) - but open doors there's almost always enough sunlight.
- manual focus only - can be advantage as well - but can be hard when not enough light.
Over all it's not the best lens, but for a hundred bucks it's quite good. Also it requires some experience to take good pics with it, because even if you see the image in the viewfinder bright it still might produce underexposed pics. Ergo use manual shutter speed.
Glass and lens quality is fine for this price.
I have a lens that will not fit my cameras mounting.
I tried to look in pentex web to see if they have a adaptor and did not find anything.
They should have said you must get an adaptor for your camera.
I have an extra one if anyone needs one.
I've just tried it a few times from my porch--focusing on my neighbors' flowers across the street (about 30 yards away) or the stop sign at the corner (about 80 yards away). Especially with the doubler and the 1000mm focal length, you'll definitely need a tripod and either a timer or a remote control to keep the camera steady.
Resolution isn't great, especially at 1000mm. However, for the price, it's hard to complain. In fact, I think it's well worth the price if you have any interest at all in trying such a high focal length lens.
One thing to watch out for: the various pieces (t-mount adapter, magnification doubler) are actually assemblies of some smaller subcomponents. They can be screwed and unscrewed or attached and detached in such a way that, for example, a piece that's intended to be part of the doubler can end up attached to the adapter when you disconnect everything. On the adapter, there's a ring inside the outer frame that's locked in place by three small bolts with hex (allen wrench) heads--those bolts can become loose. Mine did and it took me a while to figure out what was wrong. You can minimize issues if you don't overtighten when you attach the various pieces. Even if things do get detached, they're easy to put back--as long as you keep track of what belongs where!
No, it's not a lens you just slap on the front of your camera and start shooting with. I have no automatic capability with this lens no matter what mode I try to use. I just have to accept I'm shooting at f8, and I start with a best guess at my shutter speed and start from there.
If you think the lens is shooting pictures that are too washed out, underexpose a bit, or correct it in post processing, this lens is well worth the price.
To give you an idea what this lens is capable of, I'm adding a photo of a shot I took from the top of the local clock tower here in Rome, Ga. The subject is the old Normandy Dairy / Winshape Center at Berry College, 6.3 miles off in the distance late afternoon, with the sun setting off to the west behind the mountains. The images all appear for the most part to have a bluish tint to them, but this can be corrected in editing.
The top shot is the original, no cropping, full size, hand held. Low light, lens with the 2x adapter, so it was shooting at 1000mm (or what, 1200 at 35mm standard as if that matters?)
Lots of noise as is to be expected under those conditions, by the way. Not the lens' fault.
The bottom is edited in Gimp using some curves and also adding layers set to overlay, then using the paintbrush to bring out vibrant colors.
The second image shows my children in an 18mm shot and I've marked where the Winshape center is in the background.
Surreal looking, but for a shot under those conditions, I reckon I got my money's worth.
